CRUDE-OIL BURNER,

SPECIFICATION forming part of Letters Patent No. 714,467. a d NovemberAppliuation filed November 21, 1901. Serial No. 83,140. (No model.)

To all whom it may con/001%.-

Be it knownthat I, MILTON A. FESLER, a

citizen of the United States,-residing at Visalia, in the county ofTulare and State of California, have invented certain new and usefulImprovements in Crude-Oil Burners; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

Myinvention relates to the burning of crude petroleum and distillates incooking and heat- I ing stoves and all kinds of furnaces that arenotoperatedin connection withasteam-boiler, and has for its objecteconomy in the use of fuel and labor, the prevention of accidents byfire from the use of crude petroleum and distillates as fuel, freedomfrom ofiensive odors,

and the cleanliness of the place Where fuel is used. I attain theseobjects by the mechanism illustrated in the accompanying drawings,

Figure l is a perspective view showing the Fig.

vaporizing-jet and oil and steam supplying connections between thesteam-generator, oi1- regulator, and fuel-pan. Fig. 3 is an enlargeddetail sectional view of the oil-regulator.

Similar numerals refer to similar parts throughout the several views.

The entire apparatus is constructed of metal.

1 is the fire-box of a stove or furnace.

2 is a steam-cylinder placed in thefire-box and connected withawater-supply from a proper elevation through a pipe 3, having acontrolling-cock 4 and connected with the vaporizing-jet by the pipe 5.

6 is the nozzle through which the steam from the cylinder 2dischargesinto the firebox 1, and 7 .isa rotary valve having a discharge-opening 8and controlling the escape of steam through the nozzle.

9 is the oil-passage connecting the oil-supply pipe 10 with thedischarge-opening 8. j

11 is a starting cup or. pan located in'the fire-box under thesteam-cylinder 2 to hold the oil which is ignited for the purpose ofheating the steam-cylinder to make steam to vaporize the oil and startcombustion of the vaporized oil from the vaporizing-jet 8.

' 15 is an air-tight float moving in the casing 13 and connected withthe valve 16 by the stem 17. The float is raised by the oil rising inthe casing and closes the valve 16 and stops the oil-supply through thepipe 14, thus antomatically regulating the quantity of oil suppliedthrough the pipe 10 to the vaporizingjet.

18 is an ordinary three-way needle-valve casing placed in the pipe 10and through which oil is supplied to the pan 11 by means of a handle 19,needle-valve 20, and passage 21 and through which oil is also suppliedto the vaporizing-jet. I

The oil-regulator is placed at an elevation which holds the inclosed oilat a higher elevation than the needle-valve 18 and at a lower elevationthan the passage 9. This permits the oil to flow through the valve 18 byits own gravity into the pan 11, butprevents its flowing by its owngravity through the passage 9, it being carried through saidpassage intothe valve 7 by means of the suction created by the steam escaping fromthe nozzle 6. By this arrangement leakage of oil through the passage 9and valve 7 is impossible when there is no steam passing through theopening in the nozzle 6, for the flow of oil is shut ofi in the event ofthe water-supply being shut ofi from the cylinder 2 or in theevent ofcombustion ceasing in the fire-box 1.

The valve 7 has a screw-threaded connection with the nozzle 6 and isformed with a gear 22. With this gear meshes a pinion 23, carried by arevoluble stem 24: having a handwheel 25. By turning the stem throughthe medium of the hand-Wheel the valve 7 will be adjusted to regulatethe size of the outlet 8, whereby the feed of oil through the nozzle maybe controlled as desired.

The nozzle 6 is part of a burner-valve casing or union 26, havingbranches 27 and 28 coupled, respectively, with the pipes 5 and 10. Thebranch 27 has a passage 29 communicating with the nozzle, and the branch28 a passage 30, communicating withthe passage 9.

The steam passing from the cylinder 2 through the pipe 5, passage 29,and nozzle tends to create a vacuum in the outlet 8, and thus creates asuction, which draws the oil through passages 30 and 9 and unites itwith the steam at the outlet 8 and immediately converts the oil intovapor, which is forced into the fire-box 1 and there burned.

The needle 31 is placed in the steam-passage in the nozzle 6 for thepurpose of cleaning said steam-passage, which is accomplished by thesliding of the said needle in and out, the escape of the steam beingprevented by the packing-box 32 on the casing 26, through which theneedle passes.

The scale of Fig. 2 is double that of Fig. 3.

This vaporizing appliance is placed in operation by opening the valve 20and letting the oil flow into the pan 11, closing the said valve whensufficient oil is in the pan to make steam in the cylinder 2, the oil inthe pan 11 being then ignited. The cock t is then opened after thecylinder 2 has become sufficiently hot to generate steam. When the steamdischarges through the outlet 8, it assimilates with the oil, asindicated, and is ignited by the flame from the pan 11, after which theflame from the vaporizing-jet will be contin u ous and automatic as longas water and oil are supplied.

I claim- In a crude-oilburner the combination with a heater having afire box of a starting-pan located within said box, a steam-generatorlocated above the pan, a water-supply pipe extending through one side ofthe wall of the heater and connected to the generator, a steam-dischargepipe also extending through the wall of the heater and leading from saidgenerator, an oil-regulator arranged for the flow of oil therefrom tothe starting-pan by gravity, a nozzle communicating with the interior ofthe fire-box and connected with the oil-regulator and steam-pipe andlocated above the level of the oil in said regulator, the flow of oilfrom the regulator to the nozzle being produced by the suction createdby the steam discharging from the nozzle, said generator being locatedwithin the heating zones of the pan and nozzle, and suitable valvemechanism for controlling the flow of oil and steam, substantially asspecified.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

MILTON A. FESLER.
